Brea is north Orange County with range — older neighborhoods near the 57 with real mid-century bones, plus master-planned communities with newer homes. That split means two kinds of projects: updating aging systems in the older stock, and personalizing newer homes with remodels and additions. Mars Construction Industries (CSLB #1138550) covers both with four licenses in-house, from our Orange headquarters just minutes away. One team for the repipe, the remodel, and the new AC.
Construction & Remodeling Services in Brea, CA
In Brea’s older neighborhoods, we do the work old houses need: full repipes, sewer camera inspections and trenchless repair (with a 20-year lining warranty), water heater replacement, and kitchen and bath remodels where our in-house plumbers handle every rough-in. Opening a wall in a 1960s home and finding one company that can fix the plumbing, update the HVAC, and finish the room is the whole point of hiring Mars.
In the newer planned communities, it’s additions, ADUs, and finish upgrades. Growing families add bedrooms; others add an ADU through our ADU Cities brand (100+ built in four years) for income or relatives. Our builders, plumbers, and HVAC techs all work for the same company, so additions don’t stall waiting on subs.
- Kitchen, bath, and whole-home remodels for older and newer homes alike.
- Repipes, water heaters, and gas lines by licensed in-house C-36 plumbers.
- Sewer and drain services — camera inspection, hydro jetting, trenchless repair, 20-year lining warranty.
- HVAC install, replacement, and repair by our own C-20 crew.
- Room additions and ADUs — 100+ ADUs built in four years via ADU Cities.
- Commercial construction and tenant improvement for Brea’s retail and office corridors.
- 24/7 drain & plumbing emergency service via 911 Drain Lines: 714.746.7611.
Commercial property owners along Brea’s retail and office corridors get the same single-source advantage for tenant improvement and commercial construction — plumbing and HVAC in-house keeps TI schedules tight.
Why Brea Property Owners Choose Mars
Most remodeling projects fail in the gaps between trades. The plumber roughs in before the framer is done, the HVAC sub never shows, and the homeowner ends up project-managing three companies that blame each other. We built Mars Construction Industries to eliminate that problem. We hold four CSLB classifications in-house — A General Engineering, B General Building, C-36 Plumbing, and C-20 HVAC — so the crew doing your addition is the same company doing your repipe and your HVAC changeout.
We’ve been at it with 30+ years of hands-on experience, working from our Orange County home base across Southern California. We’re licensed, bonded, and insured (CSLB #1138550), and our SB-PW and SB(Micro) certifications reflect a company built to do right by the communities we serve. When you hire Mars, you get one accountable team, one phone number, and one company standing behind the finished work.
Our sister brands extend that accountability: 911 Drain Lines for drain and sewer emergencies, ADU Cities for accessory dwelling units, Get Your Roof Certified for roof certifications, and Universal Inspect for inspection services. Whatever your property needs, there’s a Mars team for it.

Frequently Asked Questions
Our home is from the 1960s. Should we remodel first or fix the plumbing first?
Fix what’s behind the walls first — or better, do it together. A repipe or sewer repair done during a remodel costs less in disruption than doing them separately, because the walls are already open. We’ll inspect your systems, show you what we find, and lay out options in one written estimate so you can decide with real information.
Are you a licensed contractor?
Yes. Mars Construction Industries Corp holds CSLB license #1138550 with four classifications: A General Engineering, B General Building, C-36 Plumbing, and C-20 HVAC. We are licensed, bonded, and insured, and we hold SB-PW and SB(Micro) small-business certifications. You can verify any California contractor’s license status at cslb.ca.gov.
How does your estimate process work?
It starts with a conversation and a walkthrough of the project. We look at the full scope, identify what each trade will need to touch, and give you a written estimate with clear, combined pricing. Because our plumbers, HVAC techs, and builders all work for the same company, we price the whole job once instead of stacking separate subcontractor bids with separate markups.
Which trades do you keep in-house?
General construction and remodeling, plumbing, drain and sewer, and HVAC are all in-house under our four license classifications. When a project also needs electrical work, we coordinate with licensed electrical subcontractors so the work stays on one schedule under one accountable team.
Do you offer emergency service?
Yes. Our 911 Drain Lines brand runs 24/7 drain and plumbing emergency service at 714.746.7611. For sewer line emergencies, we can camera-inspect the line, clear it, and talk through repair options including trenchless repair and sewer lining backed by a 20-year warranty.
Do you build ADUs?
Yes. Through our sister brand ADU Cities, we’ve built more than 100 accessory dwelling units in the last four years. From detached backyard units to garage conversions, we handle the full build with the same in-house plumbing, HVAC, and general construction crews.
